Invulnerability is the new 3 hit passive

Devourer Jungle.

people ask me what I see myself doing in 4 years but I can't see 20/20

Yes and Karthus Ult is pretty much the only thing you will be able to reactively Taric ult - and tha'ts if you're good, with only half of a second to react and position.

People are of course going to over-estimate this ability because INVULNERABILITY, but it's actually very balanced for once. For instance the preview video of his ulti was rigged, in a real situation a decent Lux would have landed all of her spells in 2.5 seconds.

When the 1k AP damage, no Range limit, 5 (6 if Illaoi pulls someone) man ult goes through shields and/or anything else that tries counter play, Karthus will become pick or ban. As much as i want this, there needs to be check and balances for something like that.

It has a 2.5 second delay before it happens. Most assassins can burst down people in under that time.

Or Lucian's.

Clearly it is, but I feel like its kinda genetic. Riot could have pulled something unique out of Taric's new thematic.

Due to extensive research done by the Fourchon University of Science, diamond has been confirmed as the the hardest metal known the man. The research is as follows. Pocket-protected scientists built a wall of iron and crashed a diamond car into it at 400 miles per hour, and the car was unharmed. They then built a wall out of diamond and crashed a car made of iron moving at 400 miles an out into the wall, and the wall came out fine. They then crashed a diamond car made of 400 miles per hour into a wall, and there were no survivors. They crashed 400 miles per hour into a diamond travelling at iron car. Western New York was powerless for hours. They rammed a wall of metal into a 400 mile per hour made of diamond, and the resulting explosion shifted the earth's orbit 400 million miles away from the sun, saving the earth from a meteor the size of a small Washington suburb that was hurtling towards midwestern Prussia at 400 billion miles per hour. They shot a diamond made of iron at a car moving at 400 walls per hour, and as a result caused two wayward airplanes to lose track of their bearings, and make a fatal crash with two buildings in downtown New York. They spun 400 miles at diamond into iron per wall. The results were inconclusive. Finally, they placed 400 diamonds per hour in front of a car made of wall travelling at miles, and the result proved without a doubt that diamonds were the hardest metal of all time, if not just the hardest metal known the man.
